Application filcrl January 31 19535. Serial No. 5,916.

Joe it known hat 1, DAVID l). Gonnon, a citizen of the United States, residing at .L

(hicngo in the county o't Cool: and State oi lllinois, have invented certain new and useful Qtmprorements in Adjustable Switch .tilountings, of which the following is a specification. i

The present invention relates to adjust able sw'tch mountings.

The present invention is useful in connection with conduits for carrying electric wires a" d will he described in connection with a canopy such as is commonly provided at the point at which a conduit extends through the wall of :1 building or other structure. The present invention content 1 5 switch mechanism in which it is de- .-a to vary the distance in the operating mechanism oi? s sv tch to the supper iug ineniher for said SW'lllt'll. According to the lllustreted embodiment of the present invention, switch controlled by a pendant operating n'iemher mounted within canopy, said switch hemp; mounted upon a conduit or pipe. The pendant member for controllinp; said switch extends through an up ertur in said canopy. It is desireble to vary the radial distance between said pendant member and the conduit referred to in order to aecommod ditlerent designs of runopv, it being det ihle that the 'iendant nieniier should hens in a teal position, or as nearly vertical as possible.

in ol st ot the present invention prom -:1= *stnble switch mom. means an tie for n'ionnting' within a can opv, which mmurting means pern'iits nth justnient of the ruieratingr mechanism ot said switch,

A further object to provide it fitting for electric li hts involving a pipe or conduit, a canopy sociated tl'ierewith, and a switch controlled by a pendant: operating member,

which operating member is adapted to (no tend through an aperture in said canopy, the parts being so arranged that said switch may be readily adjusted, within limits, (1crt-o-rding to the rz'idigil distance desired between said pendant operating; member and said pipe or conduit.

1%. further object is to provide a simple adiustuhle switch mounting which may be readily assembled and which may he readily inspected and repaired.

Further objects will appear as the description proceeds.

Referring to the drawings- Figure l is a sectional view illustrating the pipe or conduit, a canopy therefor, and w tunt controlled switching mechanism .odying the principles of the present e tionr shoving parts of the switching mechanism 1 end apart relative to one another, wherebyinspection and repairs may be readily had.

Referring first to Figure 1, the numeral indicates a well, partition, or other supporting member, through which extends the pipe, conduit, or other lamp supporting member 11. The electric translating devices supported by the conduit 11 are not illustrated inasmuch as they constitute no part ot' the present invention. The numeral ti indicates a canopy, which in the Well known manner covers the hole in the wall 11 it through which the conduit 11 extends and presents a finished appearance at the juneture of the conduit ll. with said well 10. The canopy 123 may be provided with the coller 13, which has the set screw 14 for releasnbly holding the canopy 12 in place against the wall. "lhe word wall in this sg iecitieation'is to be construed with sutli eient breadth to include theceiling ot a room.

The numeral 15 indicates as a whole certain electric switching mechanism which swigching mechanism controls the circuit of the wires 16--16. Said wires 1616 may lead to the electric translating devices sup the canopy 12 being provided with an aperture 18 for the passage of said operating member. \Yheredeasible, it is desirable to have the operating member 17 naturally assume a vertical posit-ion, whereby there will be a minimum of interference between said operating member and the canopy 12. The aperture 18 may occur at vanying distances from the axis of conduit 11, depending upon the size of the canopy and the design thereof. In order to allow the operating member 17 to hang freely it is desirable that the radial distance between saidoperatinginember 17 and canopy l2 should be adjustable. The 1. 'esent invention romises adjustability referred to. i

The present invention contemplates a pair of clamping members 19 and 20 adapted to have gripping engagement with the conduit '11. Screw bolts 2121 hold the clamping members 19 and 20 in engagement withsaid conduit 11, but permit ready adjustment of said clamping members longitudinally of said conduit 11 and circumfei'entially of said conduit. 2

The clamping member 20 has swedged therefrom the outstanding bracket 22, which carries the pivot 22, which also serves as a rivet for holding together parts to be referred to hereinafter. The immoral 23 in- 'dicates a sleeve having an end wall 23 which end wall is rotatably secured to the bracket 22 by means of the rivet Said sleeve is cut away at a portion of its circumference diammetrically spaced from the clamping member 20. Mounted within the sleeve 23, which will preferably be of metal, is an insulating sleeve 2- 1. \Vithin the insulating sleeve 2a is certain switching mechanism indicated as a whole by the numeral 25. Part of said switching mechanism 25 includes a reel, indicated as a whole by the numeral 26. The operating member 17 is adapted to operate the reel 26 to alternately open and close the circuit ot the switching mechanism 25 in response to alternate pulls upon said member 17. Rotatably supported by the bracket 22 is the guard 27, which guard has the Hat portion 28 adapted to ride uponthe bracket 22 between said bracket 22 and the end wall 23 of the sleeve 23. being pivotally supported by the rivet 22. Said guard 27 also includes an upstanding arcuate portion 29 adapted to shield the reel 26. The metal sleeve 23 and the insulating sleeve 241- are rotatable as a unit with reference not only to the bracket 22 but to the guard 27 as well. The switching mechanism 25 is non-rotatably mounted with reference to the insulating sleeve 21-. and has an outstanding portion '29 adapted to be engaged by the arcuate portion 29 of the guand 27. The metal. sleeve 23 is provided with. lugs 30, which may be turned over upon an insulating portion of the switching mechanism 25, whereby to hold said switching mechanism 25 against axial movement with reference to the sleeves 23 and 24; The operating member 17 is movable about the axis of the rivet 22 may, consequently, have its distance from the conduit 11 varied by the simple expedient of turning the sleeve 23, guard 29 and the parts housed thereby about the axis of the rivet 22. The operating member 17 is shown as extending through a guide 31 sup ported by the guard 27." It will be clear from an inspection of Figures 2 and 5 that the radial distance of the guide 31 and consequently of the operating member 17 from the conduit 11 may be varied, within limits, whereby said member 17 may extend vertically through the aperture 18, regardless of the distance (within limits) of said aperture 18 from the conduit 11.

In order that the sleeve 23 and guard 27 together with the parts housed thereby may move as a. unit about the axis of the rivet 22, the arcuate portion 29 of said guard may be provided with an upstanding lug 32 adapted to fit within a corresponding recess in the outstanding portion 29 of the switch ing mechanism \Yhen said switching mechanism 25 is located within the sleeves 23 and 2&, said upstanding lug 32, by reason of its engagement with the corresponding recess in the outstanding portion 29 of the switching mechanism 25, will cause said guard 27 and sleeve 23 to move as a unit. WVhen, however, it is desired to move the guard out of guarding relationship with the reel 26, as, for example, when any part of said reel gets out of order, it is only necessary to flex upwardly the outstanding portion 29 forming part of the switching mechanism 25 to free said plate 29 from the projection 32, whereby the guard 29 may be moved independently of the switching mechanism 25 and the sleeves 23 and 24: which house said switching mechanism. Figure 6 illustrates the position of the guard. 29 out of its normal relationship with the. plate member 29 and the switch mccha 'iism movable therewith.

It will be clear that the present invention provides a mechanism which may be readily applied and which is applicable to canopies of varying design. By simple adjustment the operating member 17 may hang vertically, or nearly so, regardless of the distance, within limits, of aperture 18 of canopy 12 from the axis of conduit 11. Moreover, the structure permits ready inspection and repairs in case inspection and repairs arenecessary. N

Though a preferred embodiment of the present invention has been described in detail, it will be understood that many modifications will occur to those skilled in the art. It is intended to cover all such modificaand tions that fall within the scope of the appended claims.
